Journal ArticleDOI
Ship hull structure monitoring using fibre optic sensors
Gunnar Wang,Karianne Pran,G. Sagvolden,Geir Bjarte Havsgard,Alf Egil Jensen,Gregg Johnson,Sandeep T. Vohra +6 more
TL;DR: It is found that fibre optic sensors are well suited for ship hull monitoring and fibre Bragg grating technology that has been employed in the composite hull embedded sensor system project (CHESS) is presented.
Development and Applications of Full-Scale Ship Hull Health Monitoring Systems for the Royal Norwegian Navy
Hans Erling Torkildsen,Aslaug Grovlen,Atle Skaugen,Gunnar Wang,Alf Egil Jensen,Karianne Pran,Geir Sagvolden +6 more
TL;DR: In this article, a ship hull structural health monitoring (SHHM) system for the Norwegian Navy is presented, which is based on the utilization of modern fiber optic sensor technology, detailed Finite Element Analysis (FEA) of the ship hull, and a modular, scaleable signal processing and data storage computer system.
Journal ArticleDOI
Wet deck slamming experiments with a FRP sandwich panel using a network of 16 fibre optic Bragg grating strain sensors
Alf Egil Jensen,Geir Bjarte Havsgard,Karianne Pran,Gunnar Wang,Sandeep T. Vohra,Michael A. Davis,Anthony Dandridge +6 more
TL;DR: In this paper, the authors used a FRP sandwich panel instrumented with a network of 16 fibre optic Bragg strain sensors, together with conventional electrical strain gauges for control and verification.
Journal ArticleDOI
Thickness vibrations of sandwich plates and beams and delamination detection
Alf Egil Jensen,Fridtjov Irgens +1 more
TL;DR: In this article, an early damage warning (EDW) system for delamination in multihull marine vehicles assembled by FRP sandwich composite materials was proposed. But the system was not tested on a single vessel.
Proceedings ArticleDOI
Instrumentation of a high-speed surface effect ship for structural response characterization during sea trials
Karianne Pran,Gregg Johnson,Alf Egil Jensen,Knut Arne Hegstad,Geir Sagvolden,Øystein Farsund,Chia-Chen Chang,Lex Malsawma,Gunnar Wang +8 more
TL;DR: In this paper, the authors report on the instrumentation of a high-speed air-cushion catamaran (Surface Effect Ship) with more than 50 fiber optic Bragg grating strain gauges, as well as conventional resistive strain gauge, accelerometers, a Motion Reference Unit and Global Positioning System.
